The third plague comes, this time without any further announcement, because Aaron stretches his staff and strikes the dust of the earth. The plague affects all people and animals. The magicians try to imitate this plague, but they don’t succeed. When life is brought forth from the dead dust, the power of satan ends. The magicians must recognize that this is the work of God.
The expression “the finger of God” is also found in Luke 11 (Lk 11:2020But if I cast out demons by the finger of God, then the kingdom of God has come upon you.). The parallel text in Matthew 12 (Mt 12:2828But if I cast out demons by the Spirit of God, then the kingdom of God has come upon you.) shows that “the finger of God” means the Holy Spirit. The law states that it is “written by the finger of God” (Exo 31:1818When He had finished speaking with him upon Mount Sinai, He gave Moses the two tablets of the testimony, tablets of stone, written by the finger of God.; Deu 9:1010The LORD gave me the two tablets of stone written by the finger of God; and on them [were] all the words which the LORD had spoken with you at the mountain from the midst of the fire on the day of the assembly.). There, “the finger of God” shows the authority of His Word. In Psalm 8 God’s creative power is described as “the work of Your fingers” (Psa 8:33When I consider Your heavens, the work of Your fingers,
The moon and the stars, which You have ordained;
Only God the Holy Spirit is able to give new life in the heart of a dead sinner, a man made from the dust of the earth’s surface. He will also “give life” to the “mortal bodies” of the believers “through His Spirit” Who dwells in them (Rom 8:1111But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you.). That will happen at the return of the Lord Jesus to take the believers to Himself. He will do this by changing the living believers and by the resurrection of the deceased believers: “Behold, I tell you a mystery; we will not all sleep, but we will all be changed, in a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised imperishable, and we will be changed” (1Cor 15:51-5251Behold, I tell you a mystery; we will not all sleep, but we will all be changed,52in a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised imperishable, and we will be changed.).
The gnats come out of the dust. In Psalm 22, dust is linked to death (Psa 22:16b16For dogs have surrounded me;
A band of evildoers has encompassed me;
They pierced my hands and my feet.
). After man had sinned, God pronounced the judgment of death: “For you are dust, and to dust you shall return” (Gen 3:19b19By the sweat of your face
You will eat bread,
Till you return to the ground,
Because from it you were taken;
For you are dust,
And to dust you shall return.”). The dust becomes gnats, which are insects that suck out blood, life, from man. Our complicated society is full of gnats. Countless people are anxious, confused, nervous, suspicious. The psychiatric institutions are becoming increasingly full. Spiritual tensions are increasing hand over hand. Many are driven to suicide. Life no longer makes sense for them, it no longer offers a future. The gnats do their destructive work.
Here, too, there is no distinction between Egypt and Israel. Many believers are swept away in the maelstrom of life. For them, life becomes an agitated existence with nerve-wracking, excessive efforts and torments. The peace and quiet have disappeared. Here too, the gnats do their destructive work.
There is a way to prevent the gnats from feasting on our blood. On that the Lord Jesus points when He says: “He who eats My flesh and drinks My blood abides in Me, and I in him” (Jn 6:5656He who eats My flesh and drinks My blood abides in Me, and I in him.). Those who find their daily rest and calmness in the death of the Lord Jesus, who take the time to occupy themselves with Him and His work on the cross, remain beyond the reach of the gnats. This also requires a certain amount of effort: you have to make time for it in your agenda and take action to spend time with Him Who said: “Come to Me, all who are weary and heavy-laden, and I will give you rest” (Mt 11:2828“Come to Me, all who are weary and heavy-laden, and I will give you rest.).
